Atmospheric particles influence the climate and harm public health. The research in Professor Hayes’ group seeks to better understand the chemistry of these aerosols, which is necessary to determine their environmental impact. In addition, the group is also interested in the chemistry of mineral surfaces.

Professor Sauvé works on the mobility and bioavailability of “traditional” contaminants like lead and cadmium, and on compounds of emerging interest, like drugs, cyanotoxins and nanoparticles. His work focuses on analyzing contaminants, their chemical speciation, environmental fate and potential impacts.

Professor Wilkinson and his group seek to understand the biophysicochemistry of biological and environmental systems. Their work is primarily aimed at improving our understanding of the bioavailability and mobility of environmental contaminants, in part by developing sensitive analytical techniques for heterogeneous systems.
